I would love to get into this game, and it did used to run on my system but with frequent crashes, but since the series of patches the stuttering and crashes are worse and now the game wont even start from the launcher. I always get the Wont Start Correctly message.
Anyone have any ideas. Dont think I will be bothering with the third one until ive seen it running and know that it wont be the same mess.

Odd. I'm on my third playthrough and even switched pc's since release and I have had only one crash so far (that's one in probably more than a 100 hours of playtime in total)

We'll probably need some more info before we can help you along:
What are you specs?
Have you tried reïnstalling the game?
Have you tried different graphics drivers?
Are you overclocking?
Is Witcher 2 the only game that crashes a lot?

Thanks. Im running an intel celeron dual core that is 2.70mhz. Graphics card is an Nvidia 560ti. Running Windows 7 32bit and have 2gig of memory.
I know that the memory could be improved along with upgrading to 64 bit but this is the only game that gives me any trouble. There are several games that I manage to run at high performance like Battelfield 3, Dishonoured, Skyrim, etc. The witcher 2 used to work when I first had it but after the second patch it just became harder to run and now just wont even start.
As far as I know im running the most up to date drivers but will double check it. Ive tried reinstalling but the same problem still persists.

Thanks for the reply. I have submitted my dxdiag file and a report to the support team. I hope that I can get it working as this is one game that I really want to finish.
